This is a hands-on technical lead role where you'll advance the state-of-the-art in marketing measurement while ensuring our current systems deliver exceptional accuracy and reliability.

You will serve as the technical architect for attribution methodologies, experiment design, and statistical inference—balancing cutting-edge research with practical business impact.

Your Impact
  • Own and advance the statistical foundations of marketing-effectiveness measurement, ensuring methodologies are robust, reliable, and scalable.
  • Research, prototype, and deploy advanced attribution and AI models for marketing measurement.
  • Design and evolve complex data science models that balance scientific rigor with practical, scalable frameworks.
  • Build and maintain experimentation frameworks for model validation and lift measurement.
  • Define and implement validation and release criteria for attribution model and product launches, including data-quality checks, model benchmarking, and validation metrics.
  • Collaborate with Software Engineers and Product Managers to (respectively) productionize and productize your work.
  • Mentor Data Scientists on complex statistical and methodological challenges, including experiment design; raise the bar for individual execution via reviews and training.

What You Bring

  • 8+ years in data science or ML engineering roles. 
  • PhD (or equivalent experience) in statistics, econometrics, machine learning, or a related quantitative field, with a strong foundation in causal inference, experimental design, and Bayesian modeling.
  • Proven experience applying statistical methods to marketing measurement, attribution modeling, and related incrementality/experiment design problems.
  • Experience in building or optimizing large-scale A/B testing or experimentation infrastructure.
  • Experience designing, deploying, and operating statistical/ML models that drive real business decisions at scale, including validation and monitoring.
  • Proficiency in Python/R/SQL and modern data platforms (BigQuery, Snowflake), familiarity with MLOps practices and data pipeline orchestration tools.
  • Strong communication skills, with the ability to explain complex statistical concepts to customers and internal stakeholders, translating technical nuance into business confidence.

Bonus Skills & Experience 

  • Experience in enterprise Martech, AdTech, B2B SaaS, or adjacent industries dealing with complex attribution challenges.
  • Experience with identity resolution across web, mobile, and offline channels.
  • Background with graph neural networks, deep learning applications.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
